I have uploaded to SIMTEL20: pd1:<msdos.voice> SAMPLE20.ZIP Digital sound playback/record (with TP5.0 src) SAMPLER provides digital sound recording (using a A/D converter connected to LPTx: or similar), and playback (using PWM on the internal speaker or with an external D/A converter). Plans for a simple resistor-based DAC are provided. Sounds are played "musically" - Pianoman tunes or keypresses can be used. (Guitar or piano keyboard layout selectable). Standard MAC sound files can be used by appending/changing the first two bytes of the file to FF FF hex., and setting the start/end arrows to remove any "garbage", and then saving the modified file to disk. (64k limit for samples). Thus MAC sounds not recorded at sample rates supported by REPLAY etc. can be played correctly on ANY speed machine. +----------------------------------------------------------------------------+ | Paul Taylor [Falcon] Victoria University of Technology (RMIT) | | s882080@minyos.xx.rmit.oz.au Melbourne, Australia. | +----------------------------------------------------------------------------+
